Worker. Length 2 mm. 



Head about \ longer than broad, a little broader behind than in front, with 

 very feebly convex sides, broadly excised and marginate posterior border and 

 sharp posterior angles. Eyes distinctly smaller than the greatest diameter of 

 the scapes, their posterior orbits at the middle of the head. Cheeks with a 

 prominently angled carina in front. Mandibles small, not flexed at the base, 

 with feebh- rounded lateral and very indistincth* denticulate apical borders. 

 Frontal carinae prominent, erect, approximated, rounded, subtruncate, but 

 not fusing behind. Frontal groove absent. Antenna! scapes thick, about 

 half as long as the head, joints 1-10 of the funiculus very short and transverse, 

 terminal joint large, glandiform, as long as the six preceding joints together. 

 Thorax narrower than the head, elongate, subrectangular, flattened above 

 and on the sides, twice as long as broad, not broader behind than in front, 

 slightly narrowed in the middle, without promesonotal or mesocpinotal sutures. 

 Anterior border of pronotum verj- straight and transverse, its superior, and 

 inferior borders as well as the superior and lateral borders of the abrupt 

 epinotal declivity marginate. Petiole nearly square, very slightly broader 

 behind than in front, narrower than the epinotmn, truncated and sharply 

 marginate in front, but not on the sides. Postpetiole shaped exactly like the 

 petiole, but larger. Gaster formed ver\' largely of the first segment, which
